The budget forecasts real gross domestic product (GDP) to grow by 2¾ per cent in FY20, about the same as actual growth in FY18, but half a percentage point stronger than the official federal Treasury forecast for the current financial year.
Household consumption accounts for 55 per cent of GDP over time. The budget forecasts it to grow by 2¾ per cent in FY20, again about the same clip as FY18, but also about a half of a percentage point faster than this financial year.
Household consumption has been sluggish for a few years now in the face of anaemic wages growth, and even then, households have been running down saving to sustain growth in by far the biggest part of the economy.
The federal government cannot do much directly to trigger an acceleration in wages growth, so the budget incorporates modest tax cuts for low to middle income earners, starting as soon as when taxpayers receive their tax returns for the current financial year.
Targeting tax cuts at lower and middle-income earners, at least in the short-term, should give the budget a bigger bang for its buck than if they were aimed at higher income earners, who would likely save rather than spend a bigger proportion of the tax cut. Which should make household consumption stronger than it otherwise would be.
But whether household consumption, and indeed the economy more broadly, grows at or above Treasury’s forecast clip in part depends on whether one or more of the key external risks overhanging the national economy were to crystallise.
Apart from the possibility that the recent recovery in global equity (stock) markets gives way to another big fall, the performance of China’s economy is by far the biggest issue for Australia’s economy in FY20 and beyond.
Canberra’s coffers have been boosted by surging prices for the coal and iron ore that are Australia’s two biggest export earners. The budget wisely assumes prices for both commodities to retreat by the end of FY20. Supply constraints for iron ore from Brazil are likely to be overcome, while environmental imperatives in China itself are equally likely to trigger a slackening in growth for both the metallurgical coal used in steel-making and the steaming coal used in power generation.
And China overtook New Zealand last year as the chief source on inbound short-term visitors (including students) to Australia. A very competitive Australian dollar in recent years has been good for tourism and educators. More generally, the trajectory of the Australian dollar is a key driver of how much local currency revenue exporters derive when they sell their wares overseas.
Treasury does not make any assumptions on the Australian dollar, other than a technical one that it remains unchanged until FY21 at the level prevailing when the budget was framed - namely “around 71 US cents”.
While federal Treasury, in common with the Reserve Bank, assumes an unchanged Australian dollar in its forecasts, the federal government’s chief mineral and energy forecaster, the Department of Industry, Innovation and Science (DISS) assumes that the Australian dollar will average 74 US cents in FY20, then 75 cents in both FY21 and FY22, then 78 cents in FY23 - the last year of Treasury’s forward estimate horizon (Figure 2).
